= !GeoExplorer =

Work has started to integrate !OpenGeo's !GeoExplorer as an alternate/replacement Map Viewing Client.

== Why? ==
 * Good for Users to use consistent tools across applications
 * Good for Developers to be part of a bigger community
 * We want to rewrite to have most of the app in static !JavaScript with [http://yuiblog.com/blog/2007/06/12/module-pattern/ module pattern] anyway
  * ease contributions from !JavaScript developers (who may be put off the Python part)
  * support caching
 * There are some [wiki:BluePrintGISGeoExplorer#GeoExplorerhaswhichMVCdoesnt cool features] available which we'd like to make use of

== Links ==
 * [http://demo.eden.sahanafoundation.org/eden/gis/geoexplorer Sahana Demo site]

 * [http://projects.opengeo.org/geoext/wiki/GeoExplorer OpenGeo Wiki]
 * [http://svn.opengeo.org/suite/trunk/geoexplorer/ OpenGeo Trunk code]
 * !OpenGeo are using !GeoExplorer as part of !GeoNode:
  * http://geonode.org
  * http://dev.geonode.org/trac
 * These tools will be merged with !GeoExplorer:
  * [http://suite.opengeo.org/geoeditor/ GeoEditor]
  * [http://suite.opengeo.org/styler/ Styler]
== Feature Comparison ==
=== !GeoExplorer has which MVC doesn't ===
 * Save personalised, bookmarkable map views (layers / viewport)
 * Browse for new WMS servers/layers
 * Google Earth 'layer'
 * Legend panel for WMS layers
 * Print support more complete
  * Warning for unsupported layers
 * Implementation of 'group' for different layer folders (can use this for Internal/External feeds)
 * Icons in top toolbar ('north') instead of Map panel title: more screen real-estate for map & potentially space for more icons (although good to keep uncluttered if possible)

=== MVC has which !GeoExplorer doesn't ===
NB It should be relatively easy to patch some of these in within Sahana (using a slightly-modified version of the existing Python code) as an interim measure to getting them added to the !GeoExplorer !JavaScript libraries.

 * Internal feature layers (do these as KML?)
 * KML/GeoRSS/GPX layers (use source 'ol'?)
 * Clustering
 * Extra OSM layers (!CycleMap, Hillshading, Taiwan, Custom)
 * Extra Google layers (!MapMaker)
 * Yahoo layers
 * Potlatch2 integration
 * HTML5 !GeoLocation support
 * !GeoNames Search
 * Overview map
 * Mouse Pointer: Lat/Lon & MGRS
 * Configurability
  * we could have each button have an enabled option?

== Issues with !GeoExplorer ==
=== Outstanding ===
 * Published maps: {{{geoexplorer/viewer.html#id}}}
  * Doesn't appear to read the config at all!
  * Viewer sends about to geoexplorer/about.html
 * How to edit Title/Abstract(Description)/Contact when saving a map?
 * How to save a WMS Server when saving a Map? ({{{"source":"source78"}}})
 * Not clear when saving whether this is a New map or an Update
  * Should have a 'Save As' option
 * No Mouse wheel to zoom
 * scaleLinePanel ugly: remove the Scale Chooser?
 * Layer-Switcher in Embedded View not as nice...why different UI (just that we have less space not a reason since we can collapse mini)
 * Currently has issues with !GeoExt 1.0 ({{{j is null}}})

=== Fixed ===
 * Ext 3.0.0 -> 3.2.1 (Test they work ok with 3.0.0 too):
  * {{{height: 27}}} (north)          [{{{GeoExplorer.js}}} & {{{Viewer.js}}}]
  * {{{header: false}}} (westPanel)   [{{{GeoExplorer.js}}}]
 * !OpenLayers 2.9 -> 2.10
  * Can remove the 'Patch the !SphericalMercator layer' from the top of {{{GeoExplorer.js}}}
 *  Debug uses version from [http://projects.opengeo.org/suite/browser/trunk/geoexplorer Suite SVN]
 *  Debug uses GXP version from [https://github.com/opengeo/gxp GitHub]
